Configuring data writing to a Firebird database


  1. The database engine has been installed (
  2. ODBC drivers for the database have been installed ( , regardless if you have a 32-bit or 64-bit operating system, install the 32-bit version of the ODBC driver).
  3. A database file for storing data has been created.
  4. A user has been created in that database, who will be given the right to write data to a database table.

Creating a table for storing the data

Below you can see the recommended SQL script for creating a table, a trigger, and a sequence. The "SYSDBA" user should run this script.


    ID int  primary key, 
    TAG_ID varchar(32) not null, 
    DATE_TIME_STAMP timestamp default current_timestamp, 
    TAG_ANTENNA_ID int, 
    TAG_FIRST_SEEN timestamp, 
    TAG_LAST_SEEN timestamp, 
    TAG_SEEN_COUNT int, 
    TAG_OUT_OF_FOV int 

set term !! ; 
 	if (NEW.ID is NULL) then NEW.ID =  GEN_ID(TAG_DATA_ID_SEQ, 1); 
set term ; !!

Selecting and configuring the data export module

To write data to the Firebird database, use the "ODBC database" module. You can select it on the "Data export" tab (Figure 6).

To configure the module, select it in the list, and click the "Configure" button below the module list.

Enable writing to the database when a window appears (Figure 7).

On the "Connection" tab (Figure 8), click the "Configure" button and add the System ODBC data source (Fig. 9 and 10).

After closing the ODBC connections administrator window, click the "Update" button and select the newly created connection in the drop-down list.

Switch to the "Linking" tab (Figure 11) or click the "Import" button. If the connection to the database was configured correctly, the application would prompt you to import the table structure from the database (Figure 12).

After importing the table structure, link table columns, and parser variables (Figure 13).

The trigger automatically fills the "ID" column in the test table, so you can safely delete that column from the list of linked columns and variables.

Save all settings of the module by clicking the "OK" button.

Now, when new data are received from the reader, the application will automatically write them to the database. If the write is successful, the application’s event log will display a message about that (Figure 14).

Tip: To display values and variables in the application’s main window (see Figure 14), you may want to set the data view, as shown in Figure 15.
